Class ThresholdMonitor

java.lang.Object

java.util.Observable

org.lsst.ccs.framework.Module

org.lsst.ccs.subsystem.common.ThresholdMonitor

All Implemented Interfaces:

Observer, org.lsst.ccs.framework.Configurable, org.lsst.ccs.framework.SignalHandler

public class ThresholdMonitor
extends org.lsst.ccs.framework.Module

Monitors a value and set alarms if goes below/above thresholds An alarm message is sent when variable goes above highLimit or below lowLimit. An alarm cleared message is sent when variable goes back between lowLimitClear and highLimitClear
